There’s a note from ESA’s Mike Steinkopf at ATV-CC earlier this evening; Mike wrote:
The ISS crew has just finished (at 22:24 CEST) the O2 repressurisation with a DP [Delta-P = change in ISS cabin pressure] of 8.9 mm Hg.
Mike was on console for the first O2 transfer from ATV-3 to the ISS; this was Gas Transfer No. 4 (ATV-3 has already delivered Air). Tonight’s first O2 ‘repress’ used ATV’s tanks 2/3 and ran for 1 hr and 45 mins starting at 20:35 CEST. 14 kg of O2 were delivered, and Flight Engineer Yuri Malenchenko took 10 minutes to start/stop the flow.
Well done, ATV-3 and crew!
Note that Station Commander Gennady Padalka & Malenchenko are also preparing for a dry run (tomorrow) for EVA-31 on Monday, 20 August.
